Cultural factors influencing Taiwanese and Norwegian engineering students’ choice of university
(European Journal of Engineering Education;35 (2), Journal article; Peer reviewed, 2010-05)Insight into factors that affect students’ choice of university is useful when designing study programmes, especially in global competition for students. This study focuses on Taiwanese and Norwegian students’ preferences ... -
Where was that photo taken? : deriving geographical information from image collections based on temporal exposure attributes
(Multimedia Systems;16 (4-5), Journal article; Peer reviewed, 2010-05-14)This paper demonstrates a novel strategy for inferring approximate geographical information from the exposure information and temporal patterns of outdoor images in image collections. Image exposure is reliant on light ... -
Approximate forward–backward algorithm for a switching linear Gaussian model
(Computational Statistics & Data Analysis;55 (1), Journal article; Peer reviewed, 2010-06-17)A hidden Markov model with two hidden layers is considered. The bottom layer is a Markov chain and given this the variables in the second hidden layer are assumed conditionally independent and Gaussian distributed. The ... -
Reference deployment models for eliminating user concerns on cloud security
(Journal article; Peer reviewed, 2010-06-17)Cloud computing has become a hot topic both in research and in industry, and when making decisions on deploying/adopting cloud computing related solutions, security has always been a major concern. This article summarizes ... -
Towards harmonious East-West educational partnerships: a study of cultural differences between Taiwanese and Norwegian engineering students
(Asia Pacific Education Review;11 (4), Journal article; Peer reviewed, 2010-07)The collaboration activities between educational institutions in the East and the West are on the increase as an increasingly globalized economy requires graduates to have the skills to work across cultural divides. Such ... -
Unsupervised and Fast Continent Classification of Digital Image Collections using Time
(Chapter; Peer reviewed, 2010-08)Advances in storage capacity means that digital cameras can store huge collections of digital photographs. Typically such images are given non-descriptive filenames names such as a unique identifier, often an integer. ... -
Deployment Models: Towards Eliminating Security Concerns From Cloud Computing
(Chapter; Peer reviewed, 2010-08)Cloud computing has become a popular choice as an alternative to investing new IT systems. When making decisions on adopting cloud computing related solutions, security has always been a major concern. This article summarizes ... -
A Fuzzy ART2 Model for Finding Association Rules in Medical Data
(Chapter; Peer reviewed, 2010-09)This paper describes a model that discovers association rules from a medical database to help doctors treat and diagnose a group of patients who show similar prehistoric medical symptoms. The proposed data mining ... -
An Energy Efficient Localization Strategy for Outdoor Objects based on Intelligent Light-Intensity Sampling
(Lecture Notes in Computer Science;6406, Journal article; Peer reviewed, 2010-10-05)A simple and low cost strategy for implementing pervasive objects that identify and track their own geographical location is proposed. The strategy, which is not reliant on any GIS infrastructure such as GPS, is realized ... -
Families of low dimensional determinantal schemes
(Journal of Pure and Applied Algebra;215 (7), Journal article; Peer reviewed, 2010-11-09)A scheme X in P^n of codimension c is called standard determinantal if its homogeneous saturated ideal can be generated by the t x t minors of a homogeneous t x (t+c-1) matrix (f_{ij}). Given integers a_0 <= a_1 <= ... <= ... -
From alien to domestic? : virtual learning environment use from a domestication perpective
(Journal of Online Learning and Teaching;6 (4), Journal article; Peer reviewed, 2010-12)This article proposes to use the concept of domestication as an analytic tool to understand patterns of use of a Virtual Learning Environment (VLE) and user attitudes towards VLEs. The data gathered includes ... -
Finding Suitable Candidates: The Design of a Mobile Volunteering Matching System
(Lecture Notes in Computer Science = Lecture notes in artificial intelligence;6763, Journal article; Peer reviewed, 2011)It can be difficult to get started with voluntary work for potential volunteers (PVs). Moreover, it is difficult to find and recruit suitable candidates for nonprofit organizations. To help solve this problem we designed ... -
Experiences Teaching Norwegian Engineering Students from a Taiwanese Perspective
(International journal of engineering education;27 (2), Journal article; Peer reviewed, 2011)This paper presents the experiences and observations of a Taiwanese scholar teaching engineering students in Norway for one semester. Many important cultural differences were found both in terms of student behaviour and ... -

A Configurable Photo Browser Framework for Large Image Collections
(Lecture Notes in Computer Science = Lecture notes in artificial intelligence;6761, Journal article; Peer reviewed, 2011)Image collections are growing at an exponential rate due to the wide availability of inexpensive digital cameras and storage. Current browsers organize photos mostly chronologically, or according to manual tags. For ... -
Déjà vu - Predicting the number of players in online games through normalization of historical data
(Chapter; Peer reviewed, 2011)A key factor to delivering a good online gaming experience is to have sufficient server resources relative to the number of players online. In this work, we present a simple profiling technique which allows effective ... -
